Forum: etree Subject: We are switching from tar to zip

As you might have noticed, we are switching the format for whole shows from tar to zip. Hopefully, fewer people have problems with zip than with tar. zip also allows one to unzip files even if the download hasn't finished yet. (Good luck finding the temporary file on Windows, though.)

All new shows will be packaged as zip. And we are converting the old tars that are out on the FreeCaches. This is taking some time during which our cache hit ratio is not as high.

BTW, we are using zip just to bundle files. We don't compress as shnf is already compressed.

To unzip you can use Winzip or PKZip on Windows, and StuffIt on Mac. On Linux there is zip and unzip which are packaged separately for some strange reason on most distributions.

If you're switching to .zip, well, so be it. But it seems to me that the .tar files download much quicker via free cache. The dowloads with .zip files seem not to work so well download-wise.

I dont know why the speed would be any different. the file sizes should be the same (maybe slightly different).

Please bring up an inconvenience or speed issues that come up... we really want to make this work well.

On the other hand, last night I downloaded delmccoury2002-07-21 from etree03, and it all worked like a charm.

Forum: etree Subject: Re: We are switching from tar to zip- speed report

Last week I was testing a low-demand item with freecache
http://www.archive.org/audio/etree-details-db.php?id=4627

(which as I reported in a previous freecache thread, I apparently snuck into a cache by accident).

Speeds last week on the .tar version were ~17 K/s before caching, ~200 K/s in first try from cache, ~100 K/s in a couple later tries.

I went to the same item using the same commercial cable connection a couple hr ago and d/l the zip. Speed was an even 30-32 K/s the whole way though.

The freecache status page shows it's in freecache01.archive.org, so I guess I pulled it from there.

Given all the variables lately with the site, any difference between now and last week is not too surprising to me.

I think items in freecache01.archive.org are not going to be particularly fast because the share the same bandwidth as the rest of our machines. My understanding is that machine is used for testing in development and will eventually disappear.

What we need now are more nodes on high speed connections (i.e. universities). If anyone knows people in CS or IT departments are their university, we would love to communicate with them about participating in the FreeCache project.
